Upward Mobility Blitz and Stealth Kill

Upward Mobility is an assassination in sequence 13 Florence. Basically you chase the target while some guards come after you.

Blitz
The fastest way to kill this target (without even moving!). At the beginning of the assassination mission the target is close enough to lock on to. The game switches your weapon to fists after the cutscene, so you will have to bring up the weapon wheel right away. After that simply lock on and shoot. I did not use throwing knives because Ezio will automatically throw them at the guards coming at him.

Stealth Kill
For this mission you are detected right away. I avoid this by bribing a herald to teleport me away from that spot. Now when I start the mission I am anonymous. However you become detected when you have a clear sight of the target, making it near impossible to kill him while remaining anonymous. I do the next best thing- remain unseen by any guards that are alerted to me. When I am first detected the minimap is yellow, indicating that the alerted guards haven't seen me. Right afterward I blend in with a group of thieves and go into superblend to be hidden. I messed up a little and almost desyncronized, but it all eventually turned out good with an in-your-face assassination that had a nice result.

I might make a video of it, but for now I'll just tell you. One time when I was trying to do that frustrating blitz I only got one of them instead of a double assassination. Then I just killed the other guy and pressed start to restart the memory. The scene after the assassination immediately happened. Some time ago I tried that again. While killing the second dude I went to the game menu. I got out of it and went back in immediately. After I did this a few times the scene after the memory corridor happened. It's strange that it lets me go to the menu since it doesn't for other assassinations, but this one is probably glitched because there are two targets.

The blitz would be very interesting for a speedrun (oh again Fed and his speedrun... bleh xD). I hadn't even thought to use the hidden gun.

Anyway, how is the end of the mission after the blitz? Is it easy to become anonymous again before reaching the next target? (I guess the optimal order is still the same, the next target being on the cathedral)

Well, I didn't try to see what the end of the mission was like since I was recording. Are you planning to make a second version of the AC2 speedrun?
(and I hope you got to see my other two blitz videos, Stabby. I'm curious as to whether the Surgical Strike blitz is valid or not.)
